Your company has outsourced certain section of business. There could be business merits while doing so nevertheless, please remember that employees are your assets and their forceful transfer to the outsourced company could generate resentment. This is turn could reduce business productivity itself. Therefore, move cautiously on this count.
Solution to this problem could be to tell that though they are told to work in outsourced company, at the time of quitting employment, their service in your company will be counted for the computation of gratuity. Find out whether it soothes their tempers. However, in such case, their new employer needs to issue them letter on the company letterhead on acceptance of the liability for the gratuity.
If the employee still do not accept your proposal then one more solution is to keep them on the roles of your company but depute them to the outsourced company. However, under such circumstances, they will be governed by the administration of that company but just salary will be given through your company.
